I note that initdb does not detect whether the data and xlog directories
are the same.  I think there is no point in addressing this only in
pg_basebackup.  If we want to forbid it, it should be done in initdb
foremost.

I'm not sure it's worth the trouble, but if I were to do it, I'd just
stat() the two directories and compare their inodes.  That seems much
easier and more robust than comparing path strings.
